Answer 2

The only normal domestic situations in which you are likely to need 50amps are for an electric shower or cooker. Both of these are subject to part P of the building regulation requirements and should only be tackled by an electrician who is part P certified, or installed and then signed off by a part P certified electrician before connection to the mains supply, who will also check the cross bonding before signing to give approval. (Any electrical supply company will tell you what size twin and earth - I can't remember having been out of the trade a few years).

Answer 3
